Steroidogenic Acute Regulatory Protein Overexpression Correlates with Protein Kinase A Activation in Adrenocortical Adenoma
The association of pathological features of cortisol-producing adrenocortical adenomas (ACAs) with somatic driver mutations and their molecular classification remain unclear. In this study, we explored the association between steroidogenic acute regulatory protein (StAR) expression and the driver mutations activating cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling to iden...
متن کاملLipoproteins regulate expression of the steroidogenic acute regulatory protein (StAR) in mouse adrenocortical cells.
The steroidogenic acute regulatory protein (StAR) is required for the movement of cholesterol from the outer to the inner mitochondrial membrane, the site of cholesterol side chain cleavage. Here we describe a novel form of regulation of StAR gene expression in steroidogenic cells. Treatment of Y-1 BS1 adrenocortical cells with either low density lipoprotein (LDL) or high density lipoprotein (H...
متن کاملSteroidogenic Acute Regulatory Protein Expression in the Central Nervous System
Locally produced neurosteroids are proposed to have many functions in the central nervous system. The identification of the steroidogenic acute regulatory protein in steroid-producing neural cells provides a new tool to understand the sites, regulation, and importance of their synthesis.
متن کاملOverexpression of steroidogenic acute regulatory protein increases macrophage cholesterol efflux to apolipoprotein AI.
AIMS In this study, we investigated the impact of enhancing cholesterol delivery to mitochondrial sterol 27-hydroxylase, via steroidogenic acute regulatory protein (StAR), on the expression of genes involved in macrophage cholesterol homeostasis and efflux of cholesterol to apolipoprotein (apo) AI. METHODS AND RESULTS Stably transfected, murine (RAW 264.7) macrophages were used to investigate...
متن کاملOxysterols regulate expression of the steroidogenic acute regulatory protein.
The steroidogenic acute regulatory (StAR) protein promotes intramitochondrial delivery of cholesterol to the cholesterol side-chain cleavage system, which catalyzes the first enzymatic step in all steroid synthesis. Intriguingly, substrate cholesterol derived from lipoprotein can upregulate StAR gene expression. Moreover, substrate oxysterols have been suggested to also play a role. To investig...
